Definitions
- the invention relates to a container - in particular one Containers with a tubular container wall - from one Light metal alloy for use as a reaction chamber in a processing process for wafers, in particular for use in wafer etching processes.
- the invention also covers a process for its manufacture.
- Such containers made of a light alloy are as Inner container for process containers in the treatment of Wafers known, in particular for performing wafer etching processes.
- Wafers are wafer-like thin slices with a thickness of less than 0.5 mm, that of single crystals of doped silicon or others Semiconductor materials are cut in order for integrated Circuits or the like electrical components used to be able to. To be able to produce a wafer after cutting a silicon ingot into wafer-thin slices lapped, etched and polished.
- the container wall is made of a metallic Material - made by extrusion - the aluminum-based material used has a magnesium content between 1.2 and 2.0% by weight with extremely small proportions of Cu, Fe, Si approximately in the order of magnitude of impurities.
- a container the container wall of which is also within the scope of the invention with a base plate made of the material mentioned on an aluminum basis with a magnesium content between 1.2 and 2.0 wt .-% is integrally formed as a container.
- Another manufacturing possibility according to the invention is the ring rolling of that container wall.
- the result can be welded sufficiently well Manufacture a tube that is also sufficiently strong for the - Container manufacturing and the use described is but not the Si that is disruptive in the wafer production process and contains Fe.
- a cross-sectionally polygonal vessel 10 is used for wafer treatment from here ten wall sections 12 with a support arm mounted on a central shaft 14 and comprising a plurality of articulated arm sections 16 for a support disk 18 for a wafer (not shown). This is removed through wall slots 20 on the one hand from a delivery station 22 and subjected to etching and cleaning processes in processing stations 24, 24 a , 24 b , and then fed to a removal station 26.
- Embodiments also polygonal - tubular body as a container wall 32 of the outer diameter d of 450, for example mm at one end a molded radial collar 34 as a support element having.
- a parallel half length a is the tubular body or the container wall 32 with a groove-shaped ring indentation 36 equipped as well as on its distal radial collar 34 End - thanks to a radial gradation 38 - with one too molded - muzzle ring 40 of the outer diameter e from here 400 mm.
- the axial length f of the muzzle ring 20 corresponds to just over a sixth of that length a of tubular body 32 engaging it.
- On radial step 38 a base plate is indicated at 42.
- the inner container 30 is made of an alloy material AlMgX shaped; its proportion of "X" in the alloy is between 1.2 and 2.0% by weight. This alloy contains the elements Cu, Fe, Si, at most in an order of magnitude of impurities.
